<p><b>syntax:</b> <i>gzip_http_version 1.0|1.1</i>
</p><p><b>default:</b> <i>gzip_http_version 1.1</i>
</p><p><b>context:</b> <i>http, server, location</i>
</p><p>Turns gzip compression on or off depending on the HTTP request version.
</p><p>When HTTP version 1.0 is used, the <i>Vary: Accept-Encoding</i> header is not set. As this can lead to proxy cache corruption, consider adding it with  add_header . Also note that the Content-Length header is not set when using either version. Keepalives will therefore be impossible with version 1.0, while for 1.1 it is handled by chunked transfers.
